Installing Optional Two - Stage Air Filter Kit
This optional two - stage air line filter is also for use on
compressed air shop systems. Filter removes moisture
and contaminants to at least 5 microns.
Connect the air supply as follows:
1. Attach the Two Stage Filter bracket to the back
of the power supply per instructions supplied
with the filter assembly.
NOTE
For a secure seal, apply thread sealant to the
fitting threads according to manufacturer's
instructions. Do Not use Teflon tape as a thread
sealer as small particles of the tape may break off
and block the small air passages in the torch.
2. Connect the two stage filter outlet hose to the
inlet port of the Regulator / Filter Assembly.
3. Use customer - supplied fittings to connect the
air line to the Filter. A 1/4 NPT to 1/4" hose
barbed fitting is shown as an example.
